Re: Math Review

Yes I understand that. The E-circle represents the entire range, the F-circle and G-circle represent the both ways the goat can go, and the H-circle (green) represents where they overlap. So would this just be considered as one area, as in just 10? Making the equation:1/4 x 10^2 x PI

Am I following the right path here?

Re: Math Review

Ok, so redoing #7 - #9:7. When the rope goes around the barn, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?Answer: 1/4 x 30^2 x PI1/4 x 900 x PI225 (PI)

8. When the rope goes around the barn the other way, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?Answer: (this would be the same as #7)1/4 x 30^2 x PI1/4 x 900 x PI225 (PI)

9. The areas you found in 7 and 8 overlap each other. How much do they overlap? What *approximate* shape do they make? What is that area?Answer:3/4 x 10^2 x PI3/4 x 100 x PI75 (PI)

---If these are right, shall we move on to #10?

Re: Math Review

Ok here is the "redo" for #7 - #10:7. When the rope goes around the barn, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?Answer: The new radius is 30. It can make up to ¼. So the area would be:1/4 x 30^2 x PI1/4 x 900 x PI225 (PI) = 706.858

8. When the rope goes around the barn the other way, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?Answer: The radius is 30. It can make up to ¼. So the area would be:1/4 x 30^2 x PI1/4 x 900 x PI225 (PI) = 706.858

9. The areas you found in 7 and 8 overlap each other. How much do they overlap? What *approximate* shape do they make? What is that area?Answer: I would say that the area is 75. It looks like it almost makes a square shape.

10. What is the total grazing area the goat can reach?Answer: To get this answer, I added up the ansers of #6, #7 and #8 then subtracted the answer from #9:1875(PI) + 225(PI) + 225(PI)  752325(PI)  757304.202  757229.202 is the final answer.
